CAR-WH EEL.

SPECIFICATION forming part of Letters Patenty No. 408,890, dated August I3, 1889. Application filed December 3, 1888. Serial No. 292,514. (No model.)

To aZZ whom t may concern:

Be it known that I, HENRY F. MANN, a citizen of the United States, residing at Allegheny, in the county of Allegheny and State of Pennsylvania, have invented or discovered certain new and useful Improvements in`j Car- Vheels, of which improvements the following is a specification.

In an application, Serial No. 290,705, filed N ovember 13, 1888, I have described and claimed a single-plate wrought-iron or steel car-wheel having as its distinguishing characteristic a vein-forced flange, the tread being united with the tread along the outer edge of the former.

The invention described herein relates to certain improvements in the wheel above referred to, and has for its object a construction of wheel wherein the iiange is re-enforced, and wherein the web (or one of them, where two are used) is connected with the tread by Jehe fold forming the reenforce of the fiange.

In general terms, the invention consists in the construction and arrangement of parts or elements, all as more fully hereinafter described and claimed.

In the accompanying drawings, forming a part of this specilication, Figure lis a sectional View of a portion of a single-web wheel embodying` my invention. Figs. 2 and 3 are similar views of modifications of the construction shown in Fig. i. Fig. 4 is a sectional view of a portion of a double web or plate wheel, and Figs. 5 and (i are similar views of modifications thereof.

In the practice of my invention I take a wrought-iron or steel disk l, of suitable dia1neter, and turn a flange along its outer edge, so as to form a shoulder or support 2, of a width approximately equal, more or less, to half the width of tread desired in the finished wheel, plus an amount of' metal sufficient to form what I term a retaining flange or rim 3. The tread 4 of the wheel is formed bya band of wroughtiron or steel having an inturned strengthenin g or bracing rib 5 along its outer edge and an outwardly-turned portion along its inner edge, said outwardly-turned portion being approximately equal to twice the depth of the desired wheel-flange- The band thus formed is then slid on over the shoulder 2 of the disk l, until the retaining-rim 3 bears against the outwardly turned portion or flange 6. The outer part of this flange 6 is then turned down against the retaining-rim 3, thereby locking the thread to the web por` tion I and forming a complete wheel-flange having a broad edge and doubly re-enforced. It will also be noticed that the portion of the tread normally in contact with the rail is in line, or approximately so,with the web, thereby rendering the tread stronger and more'rigid. If desired, the bracing-rib 5 maybe turned inwardly against the inner side of the tread, as shown in Fig. 2. In Fig. 3 is shown aform of my invention wherein the shoulder 2 of the web or disk I is made of awidth equal or ap` proximately equal to that of the tread of the finished wheel, and the web or disk is dished, as described in the application hereinbefore referred to. The tread 4 and flange 6 are formed and secured in position as hereinb'cfore described, except that for further security the bracing-rib 5 is turned in and caused to engage the body of the Wheel, as shown. This construction is especially applicable for repairing wheels of the kind shown and described in the application hereinbefore referred to, when such wheels shall have become worn or damaged from use.

In cases where the wheel is to be employed in carrying heavy loads I prefer to employ double plates or webs, as shown in Figs. 4, 5, and 6. The supplemental plate 7 is provided with an outwardly-turned flange 8, and the tread 4 is secured thereto by turning the bracing-rib 5 inwardly upon said flange 8, as shown in Figs. 4 and G; or, if desired, the

rsupplemental plate 7 maybe formed integral with the braeing-iiange 5, as shown in Fig. 5, or otherwise secured thereto.

In Fig. 6 I have shown a form of wheel wherein the flange of the finished wheel is formed by turning the rim 3 over partial iiange 9, formed on the inner edge of the tread 4, thereby forming, as in the other figures, a doubly re-enforced iiange for the wheel, but

also iirml y securing the tread to the body por" tion of the wheel.

In the single plate or web wheel shown in Figsl, 2, and 3 thehub lO is formed with a collar 11, and the web is secured thereto bya washer IOO ing in combination a web provided with a supporting-shoulder, and a tread having its flange interloeked with a rini on the supporting-shoulder by a fold of metahthereby forining a double re-enforeed wheel-llange, substantially as Set forth.

2. A wrought-iron 0r steel ear-Wheel having in combination a web provided with a supporting-shoulder, and a tread having a .flange re-enforeed by a fold of metal turned over a retaining-rini on the supporting-shoulder, substantially as set forth.

3. A wrought-iron or steel ear-wheel having in combination a Web provided with a supporti]lgwshoulder, a tread having its flange intel-locked with a rim on the supportingshoulder by a fold of metal, and a supplemental web Connected to the outer edge of the tread, substantially as set forth.

In testimony whereof I have hereunto set my hand.
